HPS Post-MAF Air Intake Tube Kit for Lexus GS350, IS350, and RC350

The HPS Post-MAF Air Intake Tube Kit for Lexus GS350, IS350, and RC350 F Sport swaps the restrictive factory rubber intake tube for a free-flowing 3-1/2 inch mandrel-bent aluminum tube, and HPS has the dyno sheets to show what that buys: +14.5 wheel horsepower and +12.6 lb-ft, with sharper throttle response and a safe air fuel ratio held throughout. The tube integrates with the factory fresh air scoop and airbox rather than fighting them, so the engine still draws cool air from where Lexus intended. HPS fine-tuned the design to put the gain in the top end of the power band, which is where a 2GR-FSE actually rewards a driver who uses it.

Development and Testing

HPS tuned the Post-MAF Air Intake Tube Kit for Lexus on the dyno rather than shipping a generic diameter and hoping for the best. The 3-1/2 inch bore was chosen to keep velocity up while removing the corrugations and steps molded into the factory rubber tube, and the result was measured at +14.5 wheel horsepower and +12.6 lb-ft with the air fuel ratio staying inside a safe window across the range. The kit does not require tuning and does not trigger a check engine light.

Construction

Mandrel bending holds a constant wall thickness and internal diameter through every curve, where press-bent tubing crushes and necks down at the bend. Aluminum pulls heat out of the charge instead of soaking it in, and it will not soften, collapse, or split with age the way the factory rubber tube eventually does. HPS pairs the tube with its race proven reinforced silicone couplers and industrial grade 100% stainless steel T-bolt clamps.

Frequently Asked Questions

How much power does the HPS Post-MAF Air Intake Tube Kit for Lexus actually add? HPS measured +14.5 wheel horsepower and +12.6 lb-ft on the dyno, with the gain concentrated in the top end of the power band. The 3-1/2 inch mandrel-bent tube removes the corrugations and steps in the factory rubber piece while holding the air fuel ratio inside a safe window across the range.
Does this fit non-F Sport GS350, IS350, or RC350 models? No. Part number 27-569 is designed around the F Sport intake tract on the 2013-2019 GS350, 2013-2019 IS350, and 2015-2019 RC350. If your car is a base or Luxury trim, please Contact us with the year and model and we will confirm the correct part before you order.
Will this throw a check engine light or require a tune? No to both. The tube replaces the section between the mass air flow sensor and the throttle body without moving the sensor or altering the airbox, and HPS validated that the air fuel ratio stays in a safe range. No reflash, piggyback, or tuning is needed.
Does it come with an air filter? No. The Post-MAF Air Intake Tube Kit for Lexus is the aluminum tube, reinforced silicone couplers, stainless steel T-bolt clamps, and the installation manual. It integrates with the factory fresh air scoop and airbox, so the vehicle keeps using the panel filter already fitted.
How difficult is the installation? Level-1. The Post-MAF Air Intake Tube Kit for Lexus installs with basic hand tools. The factory tube is clamped at each end, and HPS includes a step-by-step manual with photographs. No cutting, drilling, or other modification is required, and most owners finish inside an hour.
Why can this not be sold in California? HPS has not submitted part number 27-569 for a CARB Executive Order number, so it carries no exemption. Without an EO number the part cannot be sold in California or fitted to a pollution controlled vehicle registered there.
